Hello!
I'm trying to use the new JSON functions in Flink 1.15 to parse JSON
input data. In particular, using JSON_QUERY, I'm able to extract out
JSON array elements from a larger JSON record. However, this function
returns the JSON array as a string.
I'd like to run this array through the SQL

Hello,
In our production environment, running Flink 1.13 (Scala 2.11), where Flink
has been working without issues with a dozen or so jobs running for a
while, Flink taskmanager started crash looping with a period of ~4 minutes
per crash. The stack trace is not very informative, therefore
I had a similar need recently and ended up using
KafkaDeserializationSchemaWrapper to wrap a given
DeserializationSchema. The resulting
KafkaDeserializationSchema[Wrapper] can be passed directly to the
`FlinkKafkaConsumer` constructor.
```
class BoundingDeserializationSchema

Thanks Leonard, we are working towards 1.12 upgrade and should be able
to try upsert-kafka after that.

Hello,
I'm using Flink 1.11.2 where I have a SQL backed `Table` which I'm
trying to write to Kafka. I'm using `KafkaTableSourceSinkFactory`
which ends up instantiating a table sink of type `KafkaTableSink`.
Since this sink is an `AppendStreamTableSink`, I cannot write to it
using a generic table

Hello,
I'm trying to create a `StreamTableSource` for Snowflake using
`JdbcTableSourceSinkFactory.createStreamTableSource` (in package
org.apache.flink.connector.jdbc.table) but it fails with the following
error message due to `JdbcDialects` not having a dialect for
Snowflake.
My goal is to
Hello,
I'm writing a test for my custom sink function. The function is stateful
and relies on checkpoint restores for maintaining consistency with the
external system that it's writing to. For integration testing of the sink
function, I have a MiniCluster based environment inside a single JVM
